Because we have a really good relationship with all of our customers. Cathleen is sincere and accomodating to callers and keeps on top of projects and paperwork. Robin gives 110% in the field and knows from years of experience, how to tackle the job. Our employee's, who are paid more than minimum wage, take pride in themselves and in their work. When, from time to time, we either get a really nasty customer or a renegade employee, neither lasts long with us because we don't tolerate "bad energy!"
